@Paragrafenhexe Als jemand, der noch nicht lange versucht darauf zu achten vegan einzukaufen, bin ich immer sehr froh, wenn das schnell ersichtlich ist

Können Kartoffelchips nur mit Salz auch nicht-vegan sein? Oder ist das Werbung mit Selbstverständlichkeiten?

@Clautoffel Snus mit Tabak ist innerhaln der EU (außer in Schweden) verboten. Ob die legalen Nikotinbeutel ohne Tabak weniger gesundheitsschädlich sind, weiß ich allerdings nicht...

@JayFCox @ProfNoahGian This is because "up" and "down" are (locally) the same for everybody since gravity points in the same direction. Left and right are fully dependent on your orientation (and the meaning of the words even dependent on the context, as discussed above)

@JayFCox @ProfNoahGian Or; when you stand in a room of randomly oriented people (also standing, lying) with closed eyes and say "point to the right" they will point in pretty much random directions while when you say "point upwards" they will agree on the same direction.

I seldom spell "bureaucracy" correctly on the first try.

@nacholibray @ProfNoahGian As for top-down we just say larger z means top. If we would do the same with left-right (i.e. larger y means right) then those would not be reversed either, but this is not how we define left-right (if we define left-right as property, i.e. from the POV of each object)

@nacholibray @ProfNoahGian Let's look at the square O and define it's front as the side closest to the mirror and give it a normal vector n. The normal vector n' of the mirrored square is parallel (as in n(dot)n=+1). By definition, going mathematically positive from the front the next side is the left. 1/2

@nacholibray @ProfNoahGian n(dot)n'=+1 obviously, as opposed to antiparallel n(dot)n'=-1

@nacholibray @ProfNoahGian But this is the mirror image of the right side of the original square, so left and right are not mapped onto themselves but each other, so they are reversed.

@ProfNoahGian and should thus be indistinguishable. But: We define left and right relative to where front and back are, while we define top and bottom absolutely. If you would do the same for left and right by using your western and your eastern hand, those would not be reversed either.

@ProfNoahGian I am not entirely happy with the front-back solution that other people in the comments have proposed. While this is the first part, because the normal axis of the mirror plane is the "front-back-axis", the "left-right-" and "top-bottom-axis" both lie in the plane of the mirror

@AstridApollyon Should've answered "No I'm Astrid" instead of "Yes I am" but w/e (Astrid is a beautiful name btw)

Hahaha I’ll go die now

@MomPatronus Chronisch Entzündliche Darmerkrankungen (Morbus Crohn, Colitis ulcerosa) sind durch Blut- und Stuhluntersuchung schon gecheckt worden?

@AlmightyBogza @feelst0astman @FadeHubb It yields to the car on its right, not to the turning car

@feelst0astman @FadeHubb This is just misinformation. The car that goes straight will never yield to someone turning..

Let’s debate! Which order should the cars go?

@Hassaan_PHY Primordial Black Holes and the whole topic of theoretical astrophysics are missing

I want to build a mind map like this to put the topics in modern theoretical physics research in their appropriate place (and cross-reference them) so that upcoming young researchers can put the topics they want to work on in the proper context and how they relate to the other topics. Of course, this map is incomplete right now. Let me know if you have any suggestions for topics that I can put here. Thanks 👍 #physics #scicomm

give each pixel a random Pokemon type, and then battle pixels against their neighbors, updating each pixel with the winning type (using the Pokemon type chart) we quickly see areas of fire > water > grass > fire, electric sweeping over, ground frontiers taking over etc etc

I’m curious 👀 Without looking it up: 1. what percentage of known mushroom species do you think are POISONOUS (not necessarily deadly, but classified as poisonous) AND 2. what *country* are you from?

@annethegnome I have no clue, so my best guess would be 50% in theory. But since my gut says that while many aren't edible they are not necessarily poisonous I will correct to 40%. Germany
